Using V2V communication to create Over-the-horizon Awareness in multiple-lane highway scenarios

Abstract

This paper describes the Over-the-Horizon Awareness (OTHA) protocol which provides an extended view of the traffic ahead to Driver Support Systems (DSS) by means of multi-hop vehicle-to-vehicle communication. The protocol extends and adapts the TrafficFilter [1] to make it suitable for multiple-lane highway scenarios. As basis, we rely on the information required by the Congestion Assistant [2], a driver support system that aids drivers in traffic jams. Simulation results show that OTHA achieves high node reachability and information accuracy.
